This function opens the main window of the DALY Calculator.
After initiating the DALY Calculator main window, the following steps have to be followed to calculate DALYs:
Set the ‘Population’ table
Set the ‘Life Expectancy’ table - the default is the standard life expectancy table introduced in the GBD2010 study
Set the input parameters and corresponding distributions and stratification levels
Set the age weighting and time discounting rates
Calculate DALYs !
In order to demonstrate the calculation process of the DALY Calculator, two examples from the foodborne disease burden literature are built-in:
The burden of Taenia solium cysticercosis in Cameroon (Praet et al., 2009)
Congenital toxoplasmosis and DALYs in the Netherlands (Kortbeek et al., 2009)
In the following sections, a brief summary will be given of the functionalities
of the DALY Calculator.
A more comprehensive overview is provided in the DALY Calculator manual,
which is available through the
The DALY Calculator provides the following three menu options:
Load DALY data from file... reads population and epidemiological
data from an .RData file (through
Save DALY data to file... saves the population and
epidemiological data to an .RData file
Reset DALY calculator clears all entered data,
and resets the DALY Calculator to its default settings,
except for the life expectancy table (through

A command-line interface to the DALY Calculator
is available through the following functions:
setPop opens the ‘Population’ window
setLifeExp opens the ‘Life Expectancy’ window
setStdLE sets the standard life expectancy
setData opens a ‘Data’ window
getDALY initiates the DALY calculation process and returns the simulated results
sensitivity performs DALY sensitivity analysis
DALY_list merges different DALY objects
